Title: Earth clod separating machine from bulbs - has air passage bottom wall elastic and resistant to shock loads
IPC: A01D33/04
Filed: 1975-09-08
Abstract: Separating machine is partic. for removal of clods of earth from bulbs and root crops, these being conveyed by a transporter comprising a variable-speed feed belt and a discharge belt, an upwards air current being maintained in the transporter opening via a passage inclined upwards. The direction and volume of the current is adjustable. Separation is only partly effected by using the different material weights, but mainly by the difference in their elasticities. The bottom wall of the inclined air passage is not merely adjustable, but is also of material and thickness such as to give elasticity and resistance to shock loads. In addition, the air speed near this wall can be appreciably reduced by masking of the upper face. Thus on impact with this wall less elastic material fails to rebound enough to reach the part of the air current which is strong enough to carry it upwards.

Title: Mfr. of confectionery drops and gums - in a continuous process to attain final consistency and shape in one operation
IPC: A23G3/02
Filed: 1977-01-27
Abstract: The raw materials are metered from storage silos into a mixer in which water, glucose syrup or sugar solution is added, according to the recipe, and a homogeneous mixture is established. The mixt. is reduced to a granular form during or after the mixing. The moisture content of the product is approx. 20%. The mix then passes into the heating section of the extruder under high pressure and temp. (60-190 degrees Ce. The elastic/plastic properties of the end product vary according to the raw materials, the recipe, the metering speed, the temperature and the pressure. After heat treatment the mixt. is cooled to 30-100 degrees C and attains the required gumlike consistency before passing through a forming device such as rollers. During the final forming process, plant oil can be used to give the drops the required glaze. The material is then transported away and packed. Process is a continuous one requiring little labour, less equipment and, consequently, less space.

Title: A reactor with a mass of bacteria suspended therein to remove undesired components from a gas stream
Inventor: BRUIN JAN DE
IPC: B01D53/84
Filed: 1994-01-27
Abstract: The patent relates to a novel type of reactor for a biological purification (treatment) of a gas stream. In this reactor, the gas stream to be treated is introduced at a specific level, by means of gas distribution system, into a bacterial suspension. A uniform distribution of the gas stream over part of the horizontal cross section of the bacterial suspension may be most beneficial in this context, in connection with the liquid flow necessarily to be generated. The liquid level above the gas distribution system should be such that adequate mass transfer takes place for achieving a particular degree of purification of the gas. Owing to the good mixing, the bacterial suspension below the gas distribution system contributes some activity to the conversion of the transferred components. This allows relatively high gas loads per m2 of reactor cross section to be employed. As a result of good mixing, uniform conditions arise in the liquid phase of the reactor. That is beneficial for bacterial activity and also simplifies monitoring and control of the reactor.
